# NousResearch/hermes-agent · Race condition leaks AI agents during session close

## Open now

- Nothing open on GitHub.

These issues and fixes address a race condition where closing a TUI session mid-build can orphan or leak a freshly constructed AIAgent. The work focuses on ensuring agents are properly cleaned up when session close races with the build process.

## TL;DR

- 5 member(s): 0 open issue(s), 2 closed issue(s), 0 open PR(s), 1 merged PR(s), 2 PR(s) closed without merging.
- A fix was merged to main in PR #131328. Verify it addresses your case.
- **Recommended:** read PR #131328 (and any competing PRs below) before filing. Confirm the merged change covers your symptom.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `partially_resolved` · deciding PR(s): `pr-131328`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_PARTIAL`): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.
- Members outside that structural core may belong to a different underlying problem.
- Pairwise link density `0.34`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.
